The Effect of Different pH Water Levels on Coloring Agents in Different Flowers

Science Fair Project Information
Subject: Botany
Grade level: High School - Grades 10-12
Academic Level: Ordinary
Project Type: Experimental
Cost: Medium
Awards: None
Affiliation: Batesburg-Leesville High School (BLHS)
Description: In the experiment petals of each flower were ground in an ethanol water solution using mortar and pestle. The flower solution, at each pH level, was put in the spectrophometer at a starting wavelength of 700nm. The wavelength was decreased to 400nm by multiples of 10nm. A reading was taken and recorded at each wavelength.
